Barium fluoride (BaF2) optical component

Hellma Materials BaF2 features an excellent transmittance in the VIS and IR spectral ranges up to 12µm. This allows the usage of BaF2 as broadband optical material in the VIS and IR dual-channel systems for visible and thermal imaging. BaF2 has a lower refractive index than many other optical materials. This reduces transmission losses caused by Fresnel-reflection. Applications Hellma Materials BaF2 is an excellent optical material for a broad spectral range in VIS and IR. This enables utilization in sophisticated applications: Thermal imaging and night vision with integrated VIS channel Optics for astronomical instrumentation Infrared laser optics Scintillator for the detection of high energy γ-radiation >5Me
